Every year, more than 1 million children are exposed to sexual or physical abuse or neglect in the US. The research summarized here clearly demonstrates that exposure to stress before adulthood can result in persistent effects on both mental and physical health.

Patients with severe mental illness (SMI), such as schizophrenia, bipolar disorder, and major depression, are more likely to have experienced trauma in childhood, adolescence, and throughout their adult lives than the general population. This high exposure to traumatic events such as physical and sexual abuse and assault takes a heavy toll.
